PROCESS OF TREATING LEATHER FOR GLOVES.

No Drawing.

To all whom it may eoacem:

Be it known that we, ALBERT AARON and GEORGE M. JONES, both citizens of the United States, residing at Gloversville, Ful-.

ton county, State of New York, have invented a new and Improved Process of Treating Leather for Gloves, of which the following is a specification.

Our improvement relates to the art of treating or preparing leather for use in the manufacture of gloves, and is particularly applicable to the treatment of leather for dress gloves, although leather of other kinds may also be thus treated.

In the prior art, it has been common to treat the leather or tanned skin, preparatory to cutting it up for gloves, as follows :The

flesh side of the skin has first been smoothed.

off by pressing this side of the skin against a rapidly revolving wheel whose surface is covered with emery or some equivalent abrasive composition; during this operation the sln'n and wheel are kept wet. The skin is then colored in the usual manner, staked and shaped. Finally the grain or cuticle side of this skin is removed by pressing this side of the skin against a rapidly revolving wheel covered with emery or other suitable abrasive. This removal of the grain is effected with leather and wheel dry. In some cases, if the skin is unusually heavy, the grain side is split off with a knife, as is common in the art.

The foregoin mode of treatment has the followin disa vantages: First, the grain constituting a relatively hard and impervious coating of the skin on its side, will not readily permit the coloring material to pass therethrough and consequently the thickness of the skin can only become impregnated with coloring matter which passes into the skin from the flesh side. In practice, to carry out this step of the process so as to color the skin uniformly throughout its thickness would require a period of time Specification of Letters Patent.

' as the distance from flesh side increases. A

the leather and this heat not only hardens the skin by its direct effect-but also seems to have an independent hardening effect by reason of the action of the heat on the coloring matter. It is thought that possibly the particles of coloring matter are agglomerated or otherwise compacted and hardened. Certain it is that some effect is produced upon the coloring matter by the heating induced by the revolving wheel, which has a tendency to harden the leather.

In our improved process, we first apply the grain side of the leather to a rapidly revolving dry abrasive wheel and remove the grain. We then similarly apply the flesh side of the leather to the same or a similar wheel and smooth up the flesh side. The skin is then colored in the usual way.

According to our improved method, the

coloring material readily passes into the fore coloring, there is no heating of theleather and no consequent hardening of the same and of the particles of color with which it is impregnated after the coloring of the leather is completed.

As a result of our improved process, the final product is much softer and more velvety to the touch than is the product made by the old process first described. Furthermore,a section taken through leather treated by our improved process .will show that the leather is uniformly colored from one side to the other throughout its entire structure.

Having described our invention, we claim 1. The improvement in the art of treating tanned leather for gloves which comprises, first, tanning the leather, then removing the grain from-the outer side of the leather and the face from the inner side of the skin in the absence of moisture and in then applying a vsuitable coloring solution to the v tanned leather for gloves which comprises, 5 first, tanning the leather,-then applying a rotating dry abrasive wheel to the two faces of the leather whereby the grain is removed and the flesh side is smoothed and in then immersing the leather in a suitable coloring solution. 10

In testimony whereof we have hereunto set our hands.
